touya and yuki are so cute together!! (fangirl squeal ) ^___^ i'm sure that they're a couple by the end of the series, although it's a little more evident in the manga than the anime.
I remember I talked about this with a friend and she told me "does this means Yue has feelings for Touya too?" And up until these day, I really don't know the answer.
i've thought about that too. if yuki spends a lot of time with touya, and if yue remembers everything that happens in his disguise form, it's possible that yue would eventually get used to touya. it'd kind of be a complex situation, i think.
as for tomoyo and sakura, i think that tomoyo-chan's love for sakura is really pure too. the fact that all she wants is sakura's happiness is very touching. ^^
